Usually I get big honking bruises from IVs, blood draws, and shots. However since the medical people have discovered I am a mutant they are being more careful. I haven't had more than a faint blue-yellow mark, except for transfusion lines, in a long time. Arnica cream on the skin, and spicy food usually helped me in the past. Arnica is just magic on bruises. A bit of spice in the diet improves circulation and rinses the bruise through faster. The most dramatic I have ever had was several years back when the inside of my elbow was just black and the whole area was so swollen I couldn't move my arm right (I am assuming that the nurse was in a crazy bad mood). I put a bit of arnica on it, and then DH made a Bengal curry for supper (knocks any tex- mex, or even Thai into a cocked hat when it comes to fiery). The next morning you could barely tell where the bruising was, and my arm was no longer swollen. If you cannot handle a bit of spice in your mouth, try those capsules of cayenne or ginger.
And by the way I am now envisioning you with an eyepatch, a pirate hat with a skull and cross needles on it, a quilted parrot on your shoulder, and wearing black lace mitts. You should try it, bet it would cut quite a swathe down to the feed store.
